MAGAZINE FOR HEATING STOVES OR FURNACES.

SPECIFICATION forming part of Letters Patent No. 764, 683, dated July12,1904.

Application filed April 10, 1901. Serial No. 55,145. (No model.)

To all whom, it may concern.-

Be it known that I, EMIL SoHoUP, a citizen of the United States,residing at Lima, in the county of Allen, in the State of Ohio, haveinvented certain new and useful Improvements in Magazines for HeatingStoves or Furnaces; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which itappertains to make and use thesame, reference being had to the accompanying drawings, which form apart of this specification.

My invention relates to improvements in magazines for heating stoves orfurnaces in which either hard or soft coal is used for fuel.

The object of my present invention is to provide an improved magazinefor heating stoves and furnaces having a series of downdrafts by meansof which the hot air, smoke, and unconsumed gases generated in themagazine are conducted downward with the draft to the fire pot or grate,where they are consumed, and in the use of which a very substantialsaving of fuel is secured.

The principal novelfeature of my invention resides in the constructionand arrangement of downdraft conduits or flues by means of which the hotair, smoke, and gases generated in the magazine are conducted to thefire-pot.

My invention consists of an upright magazine of proper dimensionscentrally arranged in a suitable stove-shell and provided with a seriesof peripheral longitudinal integral draft fines or conduitscommunicating throughout their length with the interior of the magazineby means of a longitudinal slot and means for closing the upper andouter ends of said draftconduits.

Similar reference -numerals indicate like parts throughout the severalviews, in which- Figure l is a side elevation of a heatingstovecontaining my improvement, broken away in part to show the relativearrangement of the downdraft-tubes and the means for closing the same.Fig. 2 is a plan view of Fig. 1, broken away in part to show themagazine and having the ornamental top cut away. zine, taken at anysuitable point between its ends. Fig. 4 is a plan detail of theadjustable ring by means of which the natural draftopenings areregulated and closed.

The heating-stove l is of any suitable form or construction, having aproper tire-pot 2 surmounted by a proper stove-shell 3, in which issuspended or surmounted in the usual manner my improveddowndraft-magazine 4, constructed as follows: The hollow magazine 4:,open at both top and bottom, as usual, is preferably cylindrical andslightly frusto-conical and is provided upon its periphery with a seriesof integral vertical tubes or natural-draft conduits 5, preferably eightin number, extending the entire length of the magazine. These conduitsof proper capacity are open at each end and communicate freely with theinterior of the magazine by means of a narrow vertical slot 6. This slotis too small to admit any fuel, and yet is wide enough to admit thegases of the magazine freely to the said conduits, after which they arepromptly carried downward to the fire-pot or combustion-chamber by thenatural draft through said conduits. While I have shown these tubes 5 asintegral, they may be properly fixed upon said magazine, if desired, andthey may be arranged upon the inside of the magazine adjacent to itsperimeter instead of upon the outside, if preferred. My improvedmagazine thus constructed is surmounted, as usual, with a fixed top 7provided with vertical draftopenings 8 in register with the saidconduits, respectively. In a suitable annular recess in the top 7 isrevolubly mounted an annular damper-plate 9, having a series of verticalopenings 10 adapted to register with the said openings 8 when desired.These openings 8 and 10 are of proper size to properly establishanatural draft, thoughI prefer to make them of a less size than that ofthe said conduits. The said tubes or draft-conduits 5 are shown asslightly frusto-conical, though they may be of equal cross-sectionthroughout their length, ifdesired. By making the conduits 5frusto-conical or tapering it will be seen that said conduits graduallyincrease in diameter Fig. 3 is a cross-section of the maga-J and areafrom their upper ends to their lower ends, and consequently saidconduits are enabled to accommodate the body of the air as the lattergradually increases in volume in its descent through the conduits byreason of the addition thereto of the gases drawn in through the slots 6and with which the air becomes laden. Consequently by reason of suchconstruction of the conduits the latter are effectually preventedbecoming choked by the mixture of air and gases, and a free circulationthrough the conduit is maintained.

The usual openingin the top plate 7 is closed by a proper lid, as usual.(Not shown.)

The operation of my invention thus described is obvious, and, brieflystated, is as follows: When a coal fire of either hard or soft coal isstarted in the fire-pot, all the stovedampers are closed, and the onlydraft to the combustion-chamber is downward through. the said drafttubes or conduits 5, which is found by practical tests to be suflicientfor a perfect combustion. Obviously when this downward draft has beenestablished in the said conduits a suction through the said verticalslots 6 will result, thereby continually drawing from the steaming coalall the hot air, smoke, gases, and noxious fumes generated therein,which are then carried downward with the draft to the fire-pot, wherethey are consumed. The force and quantity of this downdraft can, ofcourse, be regulated or entirely shut off by means of the annulardamper-plate 9.

Numerous practical tests have demonstrated that a saving of nearlyone-half in fuel is effected by the use of my improveddowndraftmagazine.

It is apparent that my improvement is equally applicable to furnaces asto heatingstoves.

Having thus described my invention and the manner of operating the same,what I desire to secure by Letters Patent is In a stove, the combinationwith the casing or shell thereof, a fire-box located beneath said shell,and a top surmounting the shell at its upper end, said top having anannular depression provided at intervals with draft-openings, of amagazine arranged in said casing or shell and suspended from said top,said magazine having a series of peripherally-arrangedlongitudinally-extending draft tubes or conduits each of which isprovided with an inwardly-directed slot throughout its length to affordcommunication between the tubes or conduits and the interior of themagazine, the upper ends of said tubes or conduits lying directlybeneath and each registering with one of the draft-openings of the topso that each tube or conduit is fed independently of the others, saiddraft tubes or conduits also tapering from top to bottom to increasetheir di ameters and areas throughout their length, whereby said tubesor conduits are enabled to accommodate the body of air as the lattergradually increases in volume in its descent due to the addition of thegases drawn in through said slots, and are prevented becoming chokedwith the mixture of air and gases, and an annular adjustabledamper-plate fitted within the depression of the top and provided with ase ries of openings adapted to be brought into register with thedraft-openings of the top, whereby the flow of air through said openingsto the draft tubes or conduits of the magazine may be regulated.
